WeatherData

• WeatherData gives current and historical weather data for all standard weather stations worldwide.

• The location loc in WeatherData[loc, ...] can be specified as an ICAO code such as "KNYC", a WMO code such as "WMO12345", an NCDC ID such as "NCDC123456", an amateur weather station code such as "C1234", or another standardized weather station identifier.

• The location can also be given as {lat, long}, or a city specification is given of the type used in CityData, in which case WeatherData[loc, ...] gives results for the nearest high-reliability weather station.

• WeatherData[spec] gives the nearest weather station to spec for which data has ever been available.

• WeatherData[{spec, n}] gives a list of the n nearest weather stations for which data has ever been available.

• WeatherData[loc, "property", date] by default takes date to be given in UTC, and uses UTC for all output times.

• Dates can be specified in either DateList or DateString format.

• In time interval specifications {start, end, step}, step can be "Day", "Week", "Month", "Year". All gives all recorded observations.

• The option TimeZone->z allows different time zones to be assumed.

• The following settings can be used:

• Properties related to identifying weather stations include:

• WeatherData can retrieve observational weather data from meteorlogical stations throughout the world.

• Some properties may not be available until at least a few days after a given observation is made.

• Instantaneous observation properties:

• Properties aggregated over periods between observations include:

• Aggregate properties:

• Weather station properties:

• WeatherData["name", "property", ..., "form"] can give data in various forms, including:

• WeatherData["name", "property", ..., "ann"] gives various annotations associated with a property. Typical annotations include:
